Graviton trap aims to witness gravity's quantum particle
Scientists at Stevens Institute of Technology and Yale University are launching the world’s first experiment to detect gravitons, using a centimeter-scale resonator filled with superfluid helium cooled to its quantum ground state. A passing gravitational wave should impart energy that becomes a single graviton, converted into a phonon and read out with precision lasers. By scaling the detector from gram-scale to larger detectors, the team hopes to observe gravitons directly and bridge General Relativity with Quantum Mechanics, backed by the Keck Foundation.
